The deviation angle of the first bending section 111 relative to the straight reinforcing bar section is 60-90 ° (such as 66 °, 76 °, 80 °, 82 °, 84 °, 86 °, 88 °). The central angle of the arc at the transition of the ridge rib is 60-90 degrees (such as 66 degrees, 76 degrees, 80 degrees, 82 degrees, 84 degrees, 86 degrees and 88 degrees). In step 2, the iron nail 21 is a 1.5-inch iron nail 21. When the pull rods 1 are connected, the hook 11 of the next pull rod 1 is hung in the nut of the previous pull rod 1, and the hook 11 is hung in the nut from the left side of the nut, so that the square sleeve 12 is arranged upwards, and the square wood 2 can be conveniently placed.
Example 2:
as shown in fig. 10, the supporting portions 5 and the bearing portions 6 are symmetrically arranged on the left side and the right side of the ridge rib, the dust dustpan 7 support provided by this embodiment has more stability when being spanned on the ridge due to the bilateral symmetry arrangement, and meanwhile, the working surface of the bearing portion 6 is enlarged, so that the dust dustpans 7 can be respectively placed on the two sides of the sloping roof 9, and both sides of the sloping roof can be constructed simultaneously. The screened ash does not need to be conveyed to the other side across the ridge, so that the risk coefficient of construction is reduced, and the construction efficiency of tile hanging of the sloping roof 9 is improved.
From the above, the invention provides the combined ladder and the bracket for placing the dust dustpan 7, the combined ladder can provide a foot drop point for constructors on the sloping roof 9 and avoid a tile hanging working point, the bracket for placing the dust dustpan 7 on the sloping roof 9 provides a stable support for placing the dust dustpan 7, and mortar is placed during tile hanging construction. The safe construction system provided by the invention not only enhances the construction safety and ensures the safety of constructors, but also improves the efficiency of tile hanging construction of the pitched roof 9 and saves the construction cost.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
